PORT-AU-PRINCE, Haiti -- Several thousand people demonstrated in Haiti's capital on Saturday to call for the resignation of President Michel Martelly.

The protesters, aligned with opposition parties, said Martelly hasn't done enough to alleviate hunger in the impoverished Caribbean nation since he was sworn in as president in May 2011.

The demonstrators, carrying banners and chanting songs in the biggest anti-government protest of the year so far, also complained that legislative and local elections are more than two years overdue. Under pressure from the United Nations, United States and others, Martelly has said he wants to hold the vote this year but no date has been set.

The election would fill 20 of the 30 Senate seats, all the seats in the 99-member Chamber of Deputies and 140 posts at the local level.

The delayed vote was raised Friday in a meeting between Martelly and a visiting U.S. congressional delegation that consisted of Florida Reps. Ileana Ros-Lehtinen, Mario Diaz-Balart and Frederica Wilson.
